2015-02-24armv8/fsl-lsch3: Convert flushing L3 to assembly to avoid using stackYork Sun
Flushing L3 cache in CCN-504 requries d-cache to be disabled. Using assembly function to guarantee stack is not used before flushing is completed. Timeout is needed for simualtor on which CCN-504 is not implemented. Return value can be checked for timeout situation.

2015-02-24usb: musb-new: omap2430: Reset the MUSB controller earlyPaul Kocialkowski
When booting from USB peripheral boot, the bootrom will not properly deinit the MUSB controller, which doesn't clearly indicate an USB disconnection to the host and leaves U-Boot to deal with the state of the previous USB session. On some host controller drivers (e.g. xhci_hcd), this ends up in a failure during set address, caused by the lack of proper disconnection notification. Resetting the controller early in U-Boot notifies the host of the disconnection and doesn't hurt other use cases.

2015-02-23mmc: sdhci: fix bus width switching on Samsung SoCsMatt Reimer
Fix bus width switching from 8-bit mode down to 4-bit or 1-bit modes on Samsung SoCs using SDHCI_QUIRK_USE_WIDE8. These SoCs report controller version 2.0 yet they support 8-bit bus widths. If 8-bit mode was previously enabled and then an operation like "mmc dev" caused a switch back down to 4-bit or 1-bit mode, WIDE8 was left set, causing failures. This problem was manifested by "mmc dev" timing out. Signed-off-by: Matt Reimer <mreimer@sdgsystems.com>

2015-02-23mmc: exynos dwmmc: check boot mode before init dwmmcPrzemyslaw Marczak
Before this commit, the mmc devices were always registered in the same order. So dwmmc channel 0 was registered as mmc 0, channel 1 as mmc 1, etc. In case of possibility to boot from more then one device, the CONFIG_SYS_MMC_ENV_DEV should always point to right mmc device. This can be achieved by init boot device as first, so it will be always registered as mmc 0. Thanks to this, the 'saveenv' command will work fine for all mmc boot devices. Exynos based boards usually uses mmc host channels configuration: - 0, or 0+1 for 8 bit - as a default boot device (usually eMMC) - 2 for 4bit - as an optional boot device (usually SD card slot) And usually the boot order is defined by OM pin configuration, which can be changed in a few ways, eg. - Odroid U3 - eMMC card insertion -> first boot from eMMC - Odroid X2/XU3 - boot priority jumper By this commit, Exynos dwmmc driver will check the OM pin configuration, and then try to init the boot device and register it as mmc 0.

2015-02-21sunxi: Machine id hack to prevent loading buggy sunxi-3.4 kernelsSiarhei Siamashka
Right now U-Boot supports the CONFIG_OLD_SUNXI_KERNEL_COMPAT option, which makes it go out of its way in limiting the selection of PLL clock frequencies and PMIC voltages in order not to upset outdated buggy sunxi-3.4 kernel releases. And if the CONFIG_OLD_SUNXI_KERNEL_COMPAT option is not set, then booting such old kernels exhibits various failures at runtime. This is very user unfriendly, and there were already several incidents when people wasted their time being hit by these runtime failures and trying to debug them. The right solution is not to add hacks and workarounds to the mainline U-Boot, but to fix these bugs in the sunxi-3.4 kernel. And in fact, the updated sunxi-3.4 kernels already exist. Still we need to follow the 'Principle of Least Surprise' and U-Boot needs to ensure that the old buggy kernels are not getting happily booted when the CONFIG_OLD_SUNXI_KERNEL_COMPAT option is not set. And this patch addresses this particular issue. This patch makes U-Boot store the 'compatibility revision' number in the top 4 bits of the machine id and pass it to the kernel. The old buggy kernels will fail to load with a very much googlable error message on the serial console (the "r1 = 0x100010bb" part of it): "Error: unrecognized/unsupported machine ID (r1 = 0x100010bb)" This error message can be documented in the linux-sunxi wiki with proper explanations about how to resolve this situation and where to get the necessary bugfixes for the sunxi-3.4 kernel. The fixed sunxi-3.4 kernels implement a revision compatibility check and clear the top 4 bits of the machine id if everything is alright. By accepting the machine id with the bits 31:28 set to 1, the sunxi-3.4 kernel effectively certifies that it has the PLL5 clock speed and AXP209 DCDC3 voltage fixes applied. It is still possible to set the CONFIG_OLD_SUNXI_KERNEL_COMPAT option in U-Boot if the user desires to use an outdated unpatched sunxi-3.4 kernel.

2015-02-21sunxi: Set the /chosen/stdout-path fdt property for sunxi boardsHans de Goede
While discussing with some people how to get the Linux kernel to do the right thing wrt sending output to both the serial console and the hdmi out / lcd screen when booting on ARM devices, Grant Likely pointed out that there already is a solution for this. All we need to do is set the /chosen/stdout-path fdt property, and if no console= arguments were specified on the kernel commandline the kernel will honor this and add this device as a console (next to the primary video output on hdmi). And u-boot already has support for setting this, all we need to do is define OF_STDOUT_PATH and then everything will just work ootb, without people needing to meddle with adding console= arguments in extlinux.conf .

2015-02-21kbuild: prepare for moving headers into mach-*/include/machMasahiro Yamada
In U-Boot, SoC-specific headers are placed in arch/$(ARCH)/include/asm/arch-$(SOC) and a symbolic link to that directory is created at the early stage of the build process. Creating and removing a symbolic link during the build is not preferred. In fact, Linux Kernel did away with include/asm-$(ARCH) directories a long time time ago. As for ARM, now it is possible to collect SoC sources into arch/arm/mach-$(SOC). It is also reasonable to move SoC headers into arch/arm/mach-$(SOC)/include/mach. This commit prepares for that. If the directory arch/$(ARCH)/mach-$(SOC)/include/mach exists, a symbolic to that directory is created. Otherwise, a symbolic link to arch/$(ARCH)/include/asm/arch-$(SOC) or arch-$(CPU) is created.
